2008 Accord EXL. Battery is begining to get really weak. It will barely start the engine after sitting for 3 days. This battery is only 3 years old. I live in south louisiana so cold weather is really not an issue. What is some of the better batteries to buy, with a high cold cranking amperage. I've read the duralast gold, and napa legend are fairly good.

 

for many years I go to the Sears "DieHard" Gold. Has worked for me.
If take car to Sears auto store they will test your current battery & alternator, first.

I also pay them to install it (get rid of old one) and apply corrosion protection to the terminals.
Appreciate the nation-wide guarantee since I travel sometimes.
It isn't the only option, just the one I use.
